Random question- would you sell your kidney?

If offered 5 million dollars by some dying rich billionaire, its legal its a "donation". I would 5 million would last me maybe 5-10 years max. This was an actual essay question on my anatomy exam. Would you?

Most kidney problems happen to both kidneys at the same time, and it's pretty rare to have an illness specific to just one kidney (cancer is probably the big one). If you're a normal person and get a problem that affects both kidneys, it's the same has having one kidney and getting the same problem. In both cases, your kidney(s) start dying, you'll need dialysis, and eventually a transplant. So having one kidney is not that much of a disadvantage.

For five million dollars, that's a pretty easy gamble to take. You'll more than likely go the rest of your life without having any problems, even if you did the deal when young. Though I do think the billionaire should pay you more if it's a fresh, young, healthy kidney. Better products should cost more, right? 20 yr old's kidney is better than 50 yr old's!

Despite everything I just said, though, I wouldn't sell my kidney. I don't really need the money or the kidney, but maybe my future kids or something will need it. Rather they have my kidney than some old dying guy.

no not at all.
if it was for an immediate family member, that would be a completely different situation.

Nuclear weapons: A firm public commitment to build the £100bn renewal of the Trident weapons system, followed by an equally firm private commitment not to build it. They’re secret submarines, no one will ever know. It’s a win win.

It's just a principle. I wouldn't give away any body parts, even those that grow back (like spinal fluid or eggs)for any amount of money. Only exception would be my parents, children or husband if they'd die without the donation.
